Many studies on the relationships between minerals and enzymes have been conducted by several soil scientists over the past few decades. Most of these

The major research areas included the reaction kinetics, the structural and physico-chemical characteristics, and the specificity of enzymatic preparations (Dixon and Weeb, 1979). To facilitate the evaluation of complex enzymatic systems, chemical mode
